Where is the fuel pump located on a 2003 Chevy Tahoe 5.3 V8 Z71 Vin- Z flexfuel...?

Answer 1

The fuel filter is located on the inner rail on the driver side of the vehicle. If you look betweent he drives and passenger doors.under the vehicle, on the inside of the rail (i.e. opposite side of the floor board). It is there. Here is the cathc with a 2003. The fuel filter that is called for in every book is normally wrong. The 'Z' flex fuel has a special filter that requires a fuel line release tool. When you purchase a fuel line release tool. get the cheap plastic ones. I knopw it sounds wrong but they work and the expsive metal tool lever slides correctly. Hope it helps. The non-flex fuel also requires a fuel line release tool which is only a round piece of plastic with a lip.You pick the right size from the assorted sizes the kit comes in and basically force it around the fuel line fitting and push the plastic lip in into gap.Push fuel line fitting towards base of plastic ring and if done right will release fitting from old filter.At first you think the lip want fit inside the fitting but you have to work it in there with some determination.Also,when you release the fuel line coming from the fuel tank some fuel will come out under pressure.This is fine it is only the gas in the fuel line itself and will only be a few ounces.Dont forget to turn the key before starting engine to just battery for the fuel pump to fill line again.Last but not least,when you get your filter look and make sure that one end of the filter is screw coming from gas tank and the other is a nipple that goes on a steel braided rubber hose.
